Complete thoracoscopic surgery for extensive emphysema in the right upper and middle lobes caused by right B5 bronchial atresia.

Bronchial atresia is a rare congenital condition that may lead to infectious complications. Almost all patients with this condition are diagnosed early in life with normal lungs, making them particularly suitable candidates for thoracoscopic surgery. A 30-year-old man was referred to our hospital due to an abnormal shadow on chest radiography taken 7 years prior. Despite being diagnosed with B5 bronchial atresia, he refused to undergo surgical resection. Seven years later, he developed right chest pain. Computed tomography showed B5 bronchial occlusion, mucoid impaction and emphysematous changes. Treatment with thoracoscopic right middle lobectomy and S3 partial resection using four ports resulted in good lung expansion after discharge. This study highlights that thoracoscopic surgical resection should be considered in patients with bronchial atresia.
